What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
Invoice editor: Client at the top, editable line items in the middle, total and preview action at the bottom.
States: Empty draft, validation errors beside each field, exporting, and a retry action that preserves the draft.
Hypothesis: Contractors need faster repeat invoices more than more templates.
First experiment: Test duplicating a previous job with five contractors. Watch where they hesitate before expanding the feature set.
The full kit adds a phased build plan, evidence notes, tool prompts, and implementation guidance. It is a plan for your coding agent, not a finished app.
Usage: Mechanics are fair game; never reuse the original name, branding, assets, or verbatim copy.

-- Support code auto completion and automatic code formatting; -- Support debugger (breakpoints); -- Run Offline & Support File IO & Support interaction & Support multi-processing; -- Support Project References; A tiny C language development environment, support project management and header file reference, support code executing. For Coding enthusiasts and Computer-Science students, some Data-Structure projects are included. You can use the tiny environment provided to run your project locally, or you can export the project to your computer to compile and run the project. The tiny environment includes a small C standard library that supports commonly used header files and most standard C99 library functions, and C Code Develop provides a easy access header file ccd.h, also some C++ features like argument reference, iostream(cin and cout) are supported. For safety reasons, inline assembly and some other unsafe syntax are not supported. *1. Editor Support auto completion, auto format, long-press to document and other efficient features. *2. Terminal (stdin and stdout) is fully supported, and also you can open *.txt file in project use fopen(), because of the app now only support view and edit text file, you can't open file without .txt suffix or other suffix, or use binary (b) as open mode is not currently supported.

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.
From the Build Kit assessment.
A reliable timeline needs an agreed scope and a technical check. Ask your agent to estimate the phases in BUILD_PLAN.md after that review.
